I finally figured out how to sync the audio from a separate recording device with the video from the GoPro Fusion 360. The problem with all of the auto sync functions in Premier Pro is that they require good audio on the video channel to sync with. Well it turns out that the audio picked up on the GoPro is nothing but “engine drone” and even when you clapped your hands next to it you could not hear it on the video channel. I will try to post a video a little later on how I fixed it…
